Petrified Forest National Park Travel Guide
When to Go
The park is rarely crowded. Weather-wise, the best time to visit is autumn, when nights are chilly but daytime temperatures hover near 70°F. Half of all yearly rain falls between June and August, so it's a good time to spot blooming wildflowers. The park is least crowded in winter, because of cold winds and occasional snow, though daytime temperatures are in the 50s and 60s.
